# Hi3D Multiview to 3D · Multi View to 3D API

> Hitem3D mesh generation from separate front, back, left and right view images

Creates a 3D model from several views supplied through `front_image_url`, `back_image_url`, `left_image_url` and `right_image_url`, each up to 20MB. Choose a general or portrait `model` and a matching `resolution`. Texture and PBR can be toggled, `face_count` is 100,000 to 2,000,000, and export formats include glb, obj, stl, fbx and usdz.

- Run: `POST https://api.doitong.com/v1/run/hitem3d/hi3d/multi-view-to-3d`

## Pricing

Price: **$0.50 / run**. Estimated from the typical cost of one run. The quote is exactly what the run charges.

The full example input below costs $0.50 = 500 API credits (1 request × 500 API credits).

Prices are the upstream price in USD, paid from the API balance in API credits (1000 API credits = 1 USD). `POST https://api.doitong.com/v1/quote/hitem3d/hi3d/multi-view-to-3d` with the same JSON body returns the exact price for that input; the quote is exactly what a run charges. Invalid input is never charged and failed or canceled requests are refunded automatically.

## Input parameters

| Parameter | Canonical name | Type | Required | Default | Allowed values / range | Description |
|---|---|---|---|---|---|---|
| `model` |  | enum (string) | no | `hitem3dv2.1` | `hitem3dv1.5`, `hitem3dv2.0`, `hitem3dv2.1`, `scene-portraitv1.5`, `scene-portraitv2.0`, `scene-portraitv2.1` | Generation model selector: choose from the portrait- and character-tuned 'scene-portrait*' family or the general-purpose 'hitem3d*' family. |
| `resolution` |  | enum (string) \| null | no |  | `512`, `1024`, `1536`, `1536pro`, `1536fast`, `1536profast` | Generation resolution, defaulting to the model recommendation: 1024 for v1.5/v2.0 and the fast tier otherwise. Available choices are 512, 1024, 1536 and 1536pro for v1.5/v2.0; 1536fast and 1536pro for v2.1; 1536 for scene-portraitv1.5; 1536pro for scene-portraitv2.0; and 1536profast and 1536pro for scene-portraitv2.1. |
| `enable_texture` |  | boolean | no | `true` |  | Controls whether textures are generated along with geometry. |
| `enable_pbr` |  | boolean | no | `true` |  | Controls whether PBR material maps are created alongside the texture. |
| `face_count` |  | integer \| null | no |  | 100,000 – 2,000,000 | Desired face count for the generated model, overriding the partner's resolution-based recommendation. If omitted, the partner selects that recommendation, for example 500k at 512, 1M at 1024, or 2M at 1536. |
| `export_format` |  | enum (string) | no | `glb` | `glb`, `obj`, `stl`, `fbx`, `usdz` | Format used to save the generated model. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Safety screening toggle for input images: true requires a safety check before image processing begins. |
| `front_image_url` |  | string (image URL) \| null | no |  |  | Supply a front-view image by URL, using PNG, JPEG, or WebP with a file size of at most 20 MB. |
| `back_image_url` |  | string (image URL) \| null | no |  |  | Supply a back-view image by URL, using PNG, JPEG, or WebP with a file size of at most 20 MB. |
| `left_image_url` |  | string (image URL) \| null | no |  |  | Supply a left-view image by URL, using PNG, JPEG, or WebP with a file size of at most 20 MB. |
| `right_image_url` |  | string (image URL) \| null | no |  |  | Supply a right-view image by URL, using PNG, JPEG, or WebP with a file size of at most 20 MB. |

File parameters (`front_image_url`, `back_image_url`, `left_image_url`, `right_image_url`) take a public `https://` URL, a `data:` URI up to 10 MB, or the `file_url` of an upload from `POST /files`.

## Example input

Required parameters only:

```json
{}
```

A fuller example:

```json
{}
```

## Run it

Set `DOITONG_API_KEY` to a key from https://doitong.com/developers/dashboard#keys. `?wait=20` returns the finished request in the same call when it is ready within 20 seconds; otherwise poll `GET /requests/{id}` (it also accepts `?wait=`), or pass `webhook_url`.

### curl

```bash
# Run the model; wait up to 20 s for the finished result in the same call
curl -X POST "https://api.doitong.com/v1/run/hitem3d/hi3d/multi-view-to-3d?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{}'

# Still "queued" or "running"? Poll with the id from the response:
curl "https://api.doitong.com/v1/requests/REQUEST_ID?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY"
```

### JavaScript

```javascript
const API = "https://api.doitong.com/v1";
const headers = {
  "Authorization": "Bearer " + process.env.DOITONG_API_KEY,
  "Content-Type": "application/json",
};

// Run the model; wait up to 20 s for the finished result in the same call
let res = await fetch(API + "/run/hitem3d/hi3d/multi-view-to-3d?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({}),
});
let request = await res.json();
if (!res.ok) throw new Error(request.error.code + ": " + request.error.message);

// Not finished yet: long-poll until it is
while (request.status === "queued" || request.status === "running") {
  res = await fetch(API + "/requests/" + request.id + "?wait=20", { headers });
  request = await res.json();
}
if (request.status !== "succeeded") throw new Error(JSON.stringify(request.error));
console.log(request.outputs.map((o) => o.url), request.cost.credits + " API credits ($" + request.cost.usd + ")");
```

### Python

```python
import os
import requests

API = "https://api.doitong.com/v1"
headers = {"Authorization": "Bearer " + os.environ["DOITONG_API_KEY"]}

payload = {}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/hitem3d/hi3d/multi-view-to-3d", params={"wait": 20}, json=payload, headers=headers)
request = r.json()
if not r.ok:
    raise RuntimeError(request["error"]["code"] + ": " + request["error"]["message"])

# Not finished yet: long-poll until it is
while request["status"] in ("queued", "running"):
    request = requests.get(API + "/requests/" + request["id"], params={"wait": 20}, headers=headers).json()
if request["status"] != "succeeded":
    raise RuntimeError(request["error"])
print([o["url"] for o in request["outputs"]], request["cost"]["credits"], "API credits", "$" + request["cost"]["usd"])
```

### MCP

The MCP server at `https://api.doitong.com/v1/mcp` exposes the tools `search_models`, `get_model`, `quote`, `run`, `get_request`, `cancel_request`, `list_requests`, `create_upload` and `get_account`. A `run` call for this model:

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "run",
    "arguments": {
      "model_id": "hitem3d/hi3d/multi-view-to-3d",
      "input": {},
      "wait_seconds": 20
    }
  }
}
```

## Response

Every call returns a request object. `status` is one of `queued`, `running`, `succeeded`, `failed`, `canceled`. `outputs` lists the generated files with URLs on our storage (kept forever, or 7 days with `?storage=temporary`; `storage` says which); `output` is the model's own result object with the same URLs.
